Hi guys, Im toying with the idea of getting a DAC for my system. At the moment I use the Pure I20 ipod dock to connect to my amplifier and this has an inbuilt DAC. Im wondering whether upgrading to an outboard DAC such a V DAC would make a discernable difference? I've read conflicting things with some people stating there is a noticeable difference and some saying not. Any thoughts would be appreciated with any recomendations on decent DAC's below £200. Thanks.
